[摘要連結]加彭火燄鯽在水族市場上算是出現穩定但頻度與量都不大的一種非洲觀賞魚, 姑且先不論Barbus這個屬目前仍是一個分類上的垃圾桶(也就是說這個屬很可能只是一群沒有親緣關係的魚的組合), Barbus jae這條魚事實上具有兩個主要的色型, 也就是所謂的條紋型, 細點型, 還有中間型. Van den Bergh & Teugels這篇1998年論文的主旨雖然在描述兩個西非小型鯉科的新種, 但他們也對加彭火燄鯽的色彩變異提出看法. 首先, 這條魚的分布並不像某些水族網頁(如rva)所顯示的那麼狹窄, 而是廣布於幾內亞灣區北方國家以及剛果河流域的上游地區. 他們發現加彭火燄鯽的兩個色型具有中間型, 而無論是中間型, 條紋型或細點型都沒有地理分布上的差異, 同一地區的不同色型產生的原因很可能是因為季節性環境因素的波動, 而相隔很遠的族群若出現相同的斑紋則可能顯示因受環境因素所造成的趨同. 這篇文章所描述的兩個新種B. parajae與B. nounensis則尚未出現於水族市場.
Abstract
Some small-sized Barbus species (Cyprinidae), of the artificial group characterized by the absence of barbels and by an incomplete lateral line, are described from collections of fishes from the Sanaga River Basin in Cameroon, Africa. Barbus nounensis and Barbus parajae are described as new species. The problematic taxonomic position of two series of specimens is briefly discussed. A geographic morphotype of B. parajae from Congo Brazzaville is described. Morphological differences between different populations of Barbus jae are studied. Some comments are given on the description and type material of B. condei.
